ではない。BACKGROUND OF THE INVENTION Parts of civil engineering and construction machinery used for the above-mentioned purposes are usually made from wear-resistant steel, such as high-alloy manganese steel. These materials are amazing! Therefore, parts of civil engineering and construction machinery must be cast and have a structure defined by the casting, which structure is not finished to absorb wear loads. Therefore, it is not optimal.

を有する。OBJECTS OF THE INVENTION It is an object of the present invention to provide a mechanical part for civil engineering construction that can be produced by forging, has a long service life, absorbs all applied abrasive loads, and can also be used for rock crushing operations. Structure of the Invention In order to solve this problem, the present invention shows the following points. In other words, it contains at least 1% carbon as a material for civil engineering and construction materials to be extracted and/or mechanical parts of civil engineering and construction machines that are exposed to abrasive loads in contact with the civil and construction ground, in particular for civil engineering and construction machinery tools, including rock crushing tools. and the mechanical parts of civil engineering and construction machines are forged using steel to which at least one carbide-forming alloying element has been added and which (in the ground cross-section) has a fiber path that coincides with the main direction of the wear load.
